There was another discussion about this, but was more about using the 3DS as a controller and Stream Play. This thread is about creative ways Nintendo or other Developers could use both systems to enhance gameplay or reward the user in various ways. Think of this: I go out on a walk, bring my 3DS with me. Arrive home and see I got 10 Play Coins to spend. Boot up my WiiU, connect the systems and transfer those coins, so I can spend them on my WiiU system or games to get special apps, demos, in-game content and unlock misc. things, like with the 3DS! How about this?: My friend and I got the brand new Smash Bros Game. Only I got it for 3DS and he got it for WiiU. I go to his house and he is playing, I boot up my game with my 3DS and press A on "Search for WiiU Games" I see him playing so I press start, then I challenge him with my 3DS Exclusive characters… on the WiiU!! Or this?: Im playing the just-released Mass Effect: Second Universe a brand new WiiU experience. But I need extra experience points or new weapon add-ons, so I turn on my 3DS and choose Download Play, it recognizes ME:SU, and what do I see? A set of exclusive mini-games that give me WiiU in-game rewards! A similar idea could be this: Im playing a Noir-Style Detective game on the WiiU, throughout the game I find hidden special caches, I can only open them using in-game money or resources, OR I could use Download Play to see them, inside you could find hints and clues, or e-books expanding the story or giving a bit more background to the characters, maybe some caches will give you in-game money too! What else? This!!: Im playing Mario Party WiiU and I unlock pictures of the special Media Gallery, if I connect my 3DS I can see them in 3D, the same for videos, or maybe even transfer one mini-game to the 3DS to play it on the go. Aaaaaaa: After one month of the WiiU release, Swapnote U is released the app lets me exchange messages with my WiiU Friends but also, with my little brother who is playing 3DS in his room or to my online friends with 3DS. AjoiqwJhkdjhskdnas6&^%%$FS: How about a reverse situation? Instead of the WiiU giving games to the 3DS, how about the 3DS giving games to the WiiU? Mario Kart 7 had a hidden option that unlocked with the WiiU launch date. You can actually send a track and play with a friend using both systems and using the cameras you both see your faces on the screen! (Similar to how StarFox 64 3D multiplayer worked). The possibilities are endless and while you already have the WiiU Tablet and most content would have to be developed exclusively for the 3DS that does not mean it can't be done. What do you think? Share your ideas! sorry about my grammar and english, im not that pro.
